Collateral ganglia

From Wikipedia, the free encyclopedia

Collateral ganglia
Abdominal portion of the sympathetic trunk, with the celiac plexus and hypogastric plexus.
The celiac ganglia with the sympathetic plexuses of the abdominal viscera radiating from the ganglia.

Collateral ganglia (or prevertebral ganglia) are sympathetic ganglia which lie between the sympathetic chain and the organ of supply. They are the site of relay of the preganglionic sympathetic fibres that supply abdominal and pelvic viscera.

These include the celiac ganglia, aorticorenal ganglion, superior mesenteric ganglia, and inferior mesenteric ganglia.
